To all whom/imag concern: y Y

Be it known that we, vHOWARD BROWN WENTZ and JOHN BAILEY PRIDGEN, both of Charlotte, in the county of Mecklenburg and State of North Carolina, have invented a new and useful Traino-Lines Street-Painting Machine, of which the following is a specification.

The objectv of our invention is to provide a novel and eiicient machine for painting on streets and highways the lines used to designate the'direction which traffic must take, and for cleaning the street in advance p f the painting of the traiiic designating We attain theseV and other objects of our invention by the apparatus disclosed in the accompanying drawings, in which- Figure 1 is a side elevation of our invention;

Fig. 2 is a top plan view of same;

Fig. 3 is a longitudinal section on line 3-3 of Fig. 2;

Fig. 4 is a detail transverse sectional View on line 4 -4 of Fig. 2;

,Fig. 5 is a detail longitudinal view on line 5-5 of Fig. 2; and

Fig. 6 is a horizontal section on line 6-6 of Fig. 5.

f Like numerals designate like parts in each of the several views.

Referring to the accompanying drawings, we provide a main frame 1 on which is mountedk a suitable tank 2 to contain the paint. We further provide suitable handles 3 for manually operating the machine and a suitable cross-bar 16 extending between said handles. Frame 1 is supported by a single front wheel 5 and by two rear wheels 4 which are/mounted on the axle 9. Axle 9 also carries the drum 8 which drives the belt 7 which in turn drives the rotating brush 6, which brush is positioned in advance of the painting brush 23 and cleans the portion yof the street ywhichv is to be painted with the traic direction line. The brush 6 is a spiral brush and therefore sweeps the dirt to one side of the machine.

The axle 26 of brush 6 is mounted on arms 24 which are pivotally attached at 25 to frame 1 so as to permit the brush lowering or raising itself according to the surface over which it is travelling. We provide a suitable valve controlled drain pipe 10 Opening out of the bottom of tank 2, as shown in Fig. 1. We alsor providea suitably sup-v ported feed pipe 11 opening out of tank 1 and extending to a po1nt in front of and in proxnnityv to the painting brush 23, which brush is mounted in a suitable socket or bracket 27. Feed pipe 11 is preferably provided at its lower en or spreading nozzle which functions to spread the paint over the entire surface in advance of the paint brush 23 instead of pouring it out through the restricted end of one pipe. f y

We prefer to provide a suitable ball and socket or other universal joint 12 in a suitable portion Of pipe 11 whereby to permit of adjusting the position of that pipe'by any suitable adjusting means, such as the adjustable bracket 13 indicated in Fig. 6. We provide a' suitable'valve 14 in feeding pipe 11, foropening or cutting OE the How of paint through pipe 11. Valve 14 is oonwith a fan shaped trolled by a suitable handle 15, the endof which is rotatably mounted in and supported by cross rod 16 carried near the ends of handle 3, as shown in Figs. 1 and '2.1

We provide suitable side and guard plates 17 arranged at each side of the brush 23 and in proximity thereto for guiding and limiting the expanse of the line of paint. These side plates 17 are in the form of runners and are adjustably supported by rods 18 mounted in the slotted portions 22 of ide brackets 21. l Rods 18yare mounted in ushings 28 which function to keep therods 18 steady and stationary. Were the rods free to move from side to side `it Vwould cause the line of paint to be irregular. Therefore the provision of bushin 28 is desirable. They do not, however, interfere with the up and down `motion of guard 17.

We further provide springs 19 and 20 which exert downward pressure on the runners 17 The rear spring 20 is heavier than the front spring 19 to insure a better operaloo tion of the device.

In operating the'invention, the machine is 'it in adjusted the drum 8 is'driven, as will be obvious from Fig. l of the. drawings. Owing to the spiral shape of brush 6 and the fact that it extends over a greater width of surface than the space between guards 17 it functions to throw all of the dirt beyond both of the sides of the guard instead of merely pushing `the dirt along in front. The runners 17 enclose the paint so that it is spread by the brush when Within the space between the runners, the runners being resiliently held in place by the spiral springs 19 and 20f which encircle the rods18 and press downwardly on top of the runners, as shown. This method of mounting the runners permits of their riding over obstructions in the street without interfering with the successful operation of the device. The valve controlled drain pipe 1() permits of readily cleaning out the tank 2 whenever desired.

The term street, as used in this specification and in the following claims, is to be construed as including highways or any road adapted to receive'traiic direction line painting.

lVhat we claim is 1. In a traffic line street-painting ma-v chine, the combination of a wheeled frame, a paint tank mounted on the frame, a painting brush positioned under the frame, resiliently suspended runners arranged on each side of the paint brush, means for discharging paint in front of the brush, a rotatable brush positioned in advance of the paintv brush to sweep the street, and means for rotating said brush while the machine is in operation. V

2. Ina traffic line street-painting machine, the combination of a wheeled frame,

a paint tank mounted on the wheeled frame, a line painting brush suspended from the fram'e, a feed pipe extending from the tank to a point in advance of and in proximit to the brush, a valve in the path' of the eed pipe, an extended handle for operatingsaid valve, the aforesaid feed pipe including a universal joint to permit of its adjustment to any desired position, and means for securing osition.

3. In a tra ck line street-painting 4machine, the combination of a Wheeled frame,

paint tank mounted on the wheeled frame, a line painting brush suspended from the frame, a valve-controlled feed pipe extending frornthe tank to a point in advance of the brush, said feed pipe including a universal joint, `and means for fastening the pipe in an. adjusted position.

4. In a traffic line street-painting machine, the combination of a Wheeled rame, a paint tank mounted on the Wheeled frame', the paint tank having a valve-controlled discharge pipe, a feed pipe extending from the tank to a point in proximity to the ground,v

a stationary paint brush positioned rearwardly relative to the kfeed pipe outlet, resiliently mounted runners disposed on either side of the paint brush to control the flow of paint, and a rotating brush positioned in advance of the paint brush and arranged to be driven automatically when the painting machine is pushed along.

5. In a traffic -line street-painting machine, the combination of a wheeled frame, a paint tank mounted on the wheeled frame, a valve-controlled feed pipe extending from the tank to a point in proximity to the street, a stationary paint brush suspended from the frame at a position rearward of the outlet of the feed pipe, resiliently mounted runners disposed on either' side of the paint brush to regulate the surface over which the paint is spread, said runners having a greater degree of tension applied to their rear portions, and means for sweeping the street at a p oint in advance of the paintingY brush.

G. In la tratiic line street-painting machine, the combination of a Wheeled frame, o

a paint tank mounted on the frame, a ainting brush positioned under the rame, resiliently suspended runners arran ed on each side of the paint brush, means or discharging paint in front of the brush, a spiral rotatable brush positioned in advance of the paint brush to sweep the street, pivotally mounted means supporting the axle of the brush to permit of automatic adjustment of the brush in use, and means for rotating the brush while the machine is in operation.

7. In a traffic line street painting machine, the combination of a wheeled frame, a paint tank mounted on the wheeled frame, a valve controlled feed pipe extending from the tank to a point in proximity to the ground, said feed pipe having a fan-shaped nozzle at its end, a paint brush suspended from the frame rearwardly of the, aforesaid nozzle, means for confining the line of paint to a predetermined area and automatically operated means for cleaning the street' HOWARD BROWN WENTz JOHN BAILEY PBIDGEN.
